My cat Hunter apparently had a nosebleed tonight. He was sneezing fine droplets of blood, and had long strands of bloody boogers hanging from his nose. The blood was fresh (bright red, not the deeper red of old/dried blood).
He has chronic sinus infections that we occasionally treat with antibiotics when they seem particularly bad (his breathing becomes louder because of the congestion), but we've been unable to cure the sinus problems.
He is 10 years old, and neutered. He's currently being treated for an unknown parasite (he was gassy and his eosinophil count was high, but we were unable to identify the specific parasite, so he had two doses of a dewormer, 1 month apart. The second dose was 3 days ago).
I dripped some saline into his nose to try to stop the bleeding (until he sneezed out non-bloody boogers), but I'm not sure if this was the best treatment. If it happens again, should I do anything, and if so, what?
